Dried bark primarily from broadleaf trees (oak, konara oak, abemaki oak, and kashi oak). Packed in 7.5kg boxes, mostly dome-shaped and wide pieces! Perfect for insect breeding, handicrafts, etc. ◎ Shipping via Sagawa Express. We apologize, but we cannot ship to Okinawa, Hokkaido, and remote islands. We appreciate your understanding. ◎ As this is bark that has been naturally dried, small insects may occasionally be present. Please be aware of this when storing indoors, and only purchase if you understand this. Thank you for viewing. We look forward to your consideration.
